At the #NKFClinicals to see @rajmehrotra1122 win the Michael Lazarus distinguished scholar award. Image
His lecture begins, “Consider the patients’ lived experience” #NKFClinicals

Dr: “Labs look good”
Patient: “but doctor why do I feel like crap” ImageImage
Dialysis is a 4-6 hour time commitment. There is no other chronic condition that takes a greater commitment by patients.

One way to help patients is give them a choice of modality.

#NKFClinicals
The past:

Home dialysis is for some people by some doctors for some time

And this is an improvement from the truly horrible

“PD is a second class therapy for second class patients provided by second class doctors”

#NKFClinicals
PD is good #NKFClinicals
There is no difference in mortality PD v HD ImageImage
As we have expanded the PD population we are not adding people that are bad candidates that may do worse. Not happening. New additions are doing fine. #NKFClinicals

#NKFClinicals Image
Wow. @rajmehrotra1122 is giving a masterclass on delivering a compelling keynote. Great slides. Powerful message. #NKFClinicals Image
The second half of his talk will focus on symptom management.

So much research focused on mortality, but one of the top complaints in fatigue. We should be paying attention to dialysis associated fatigue. It doesn’t always have to be mortality. #NKFClinicals Image
Doctors think the solution to every problem is more dialysis
Patients want the least amount of dialysis necessary. #NKFClinicals
Depression should he treated and addressed regardless of the downstream effect. #NKFClinicals Image
Not all uremic symptoms gets better with dialysis.
Appetite does improve with dialysis
Dyspnea gets better with dialysis
Total number of symptoms does not go done with dialysis
Depression does not improve with dialysis

#NKFClinicals Image
More dialysis did not improve insomnia.
Shown in both HEMO and FHN #NKFClinicals ImageImage
Cognitive behavior therapy is effective but is a big ask for people that are already going to dialysis three days a week. #NKFClinicals
A shout out to CKD associated pruritus and difelikefalen #NKFClinicals ImageImage

Despite calling it “laboratory error”, a lot of the problem happens long before the sample gets to the lab. #NKFClinicals Image

Starting with pseudohyponatremia
These are real cases
The osmolality was 294, so there is a huge gap. 44ish

I presented a poster at #NKFClinicals. This came from working with ViforCSL on the KALM-1 and KALM-2 meta-analysis of the pivotal trials of difelikefalin for CKD associated pruritus (CKDaP). About a year ago we brainstomed what other lessons could we could pull from the data. Image
A question we had was how quickly do people respond to the drug, or put more practically, if you start a patient on difelikefalin and a month later they are still having intense itch, how likely will it be that they still could respond?
Look at the only figure on the poster and focus on the bars, this gives the fraction of people who will ultimately respond to difelikefalin who have responded at 4 weeeks, 8 weeks and 12 weeks. Image

Never in the history of medicine has so much been done, by so many, so incompetently, with so little consequence as in the treatment of severe hyponatremia. #Tweetorial 1/10
You shouldn't correct hyponatremia too fast. The speed limit is 8 mmol/L per day. We are terrible at it. In George et al, 41% of 1,490 pts were corrected faster than 8 mEq/L. Look at the poor slobs at the left of the nomogram whose Na actually went down 🤪 2/10
Thankfully this incompetence is rarely punished. Of the 611 (41% of 1490) patients who over-corrected in the George trial, only 7 developed osmotic demyelination syndrome (ODS). Screw the sodium correction and you can get away with it 99% of the time. 3/10

The begining of my medical career was dominated by HIV

Start med school in 91. Magic Johnson announces he is HIV+
MS3 med students do blood draws on HIV+ patients (phlebotomy refuses)
MS4 lost my first patient, advanced dementia HIV
Graduated in '95, peak HIV, 50k US deaths
The whole clincal world was HIV, but you would go to the textbooks and they would still be calling HIV HLTV3. It was bonkers. It was in this envirnoment that UpToDate crushed Harrisons.
Then during residency HAART emerges and the whole thing melts away in a matter of years. All that knowledge about opportunistic infections becomes less a critical part of IM and selective ID knowledge.
